Unlevered yield in real estate is a property’s net operating income divided by the total cost to acquire and prepare it, expressed as a percentage. The formula strips financing out of the picture entirely, so two buildings with different loans can be compared on what the real estate itself actually earns. Institutional investors and private equity firms lean on it for exactly that reason.
Unlevered Yield = (Net Operating Income ÷ Total Investment Basis) × 100
The math is the easy part. The honesty of the number depends entirely on the two inputs.
Calculating Net Operating Income
Net operating income sits on top of the formula, and getting it right matters more than any other step. Start with gross potential income, which is the rent the property would collect if every unit were leased and every tenant paid in full. Subtract vacancy and credit losses to reflect reality.
Vacancy rates vary sharply by property type. Office space nationally averaged around 14% in mid-2025, retail sat closer to 4%, and industrial hovered near 7–8%. Plugging in a blanket 5% vacancy assumption across all asset classes is one of the fastest ways to produce a misleading yield.
Then subtract operating expenses: property taxes, insurance, utilities, maintenance, and management. The OCC’s underwriting guidance notes that operating expenses for commercial properties generally fall between 35% and 45% of revenue, with older buildings and those where the landlord covers heat or water landing at the higher end.1Office of the Comptroller of the Currency. Comptroller’s Handbook – Commercial Real Estate Lending Multifamily management is typically underwritten at around 5% of revenue.
The rule that makes this yield “unlevered” lives here: debt service stays out of NOI. Interest, principal, and loan fees have nothing to do with how the building performs operationally. The OCC handbook frames NOI as a stabilized estimate of income and expenses precisely so it can be compared across properties regardless of financing. Analysts typically work from either a trailing twelve-month statement or a forward-looking pro forma, depending on whether they’re measuring current performance or projected stabilization.
Building the Total Investment Basis
The denominator needs to capture every dollar spent to acquire and prepare the property. The purchase price is the starting point, but rarely the ending point.
Closing costs on commercial deals add real weight: legal fees, title insurance, transfer taxes, and recording fees. Immediate capital expenditures needed to bring the building to its intended condition also count. A roof replacement, parking lot resurfacing, or HVAC overhaul done at acquisition goes into basis because the property couldn’t produce its projected income without that work.
In syndicated deals, sponsors typically charge an acquisition fee to cover sourcing, underwriting, and closing. That fee is part of the capital deployed and belongs in the denominator. Environmental assessments, appraisals, and surveys get rolled in as well. Leave out a six-figure renovation or a substantial closing cost and you’ll overstate the yield while understating your actual exposure.
A Note on 1031 Exchange Basis
If the property was acquired through a like-kind exchange under Section 1031, the investment basis for tax purposes carries over from the property given up rather than resetting to the new purchase price.2Office of the Law Revision Counsel. 26 U.S. Code 1031 – Exchange of Real Property Held for Productive Use or Investment The IRS has confirmed this carryover basis preserves deferred gain and generally produces a lower depreciable basis than a taxable purchase would.3Internal Revenue Service. Like-Kind Exchanges Under IRC Section 1031 For unlevered yield, most analysts still use the actual economic cost of the new property as the denominator, because they’re measuring cash performance, not tax outcomes. If you’re also running an after-tax analysis, the split between economic basis and tax basis matters.
A Worked Example
A property producing $500,000 in NOI against a total basis of $10,000,000 has an unlevered yield of 5.0%. That’s what you’d earn annually if you paid all cash. Clean, debt-free, comparable across markets.
Where analysts trip themselves up is upstream, in the inputs. An aggressive vacancy assumption or an omitted capital expenditure doesn’t change the division. It just produces a yield that looks better than the property actually earns.
Unlevered Yield vs. Cap Rate
The confusion between unlevered yield and capitalization rate catches experienced investors, because the formulas look nearly identical. Both divide NOI by a dollar figure. The difference is which dollar figure sits underneath.
A cap rate uses the property’s current market value. Unlevered yield, often called yield on cost, uses total project cost, including purchase price, closing costs, and capital improvements.
That distinction matters most on value-add and development deals. Buy a property for $8 million, spend $2 million on renovations, and stabilize NOI at $600,000, and your yield on cost is 6.0% ($600,000 ÷ $10,000,000). If the renovated building is now worth $12 million on the open market, its cap rate is 5.0% ($600,000 ÷ $12,000,000). The 100 basis-point spread between those two numbers is the value the work created. Developers generally target 150 to 250 basis points of spread above the prevailing market cap rate to justify the execution risk. When yield on cost barely exceeds the market cap rate, you took construction or renovation risk for little incremental return.
How Financing Changes the Return
The whole point of the “unlevered” label is to separate this metric from its leveraged counterpart. When you finance part of the purchase, your equity investment shrinks and your annual cash flow gets reduced by debt service. Levered yield, sometimes called leveraged cash-on-cash return, divides after-debt cash flow by the equity you actually invested. Leverage amplifies returns when it works and destroys them when it doesn’t.
Take a $10 million property producing $500,000 in NOI, a 5.0% unlevered yield. Put down $4 million, borrow $6 million on terms requiring $350,000 in annual debt service, and after-debt cash flow is $150,000 on $4 million of equity. That’s a 3.75% levered yield. Leverage actively hurt returns because the cost of borrowing exceeded what the property earns. This is negative leverage: the levered return falls below the unlevered return because the loan constant outpaces the property’s yield.
Negative leverage became widespread after interest rates rose sharply in 2022 and 2023. Buyers who underwrote at 4% cap rates suddenly faced borrowing costs above 6%, and every dollar of debt dragged their equity returns down. Comparing unlevered yield against expected cost of debt before closing is one of the simplest and most important checks in real estate underwriting. If the unlevered yield doesn’t comfortably exceed the loan constant, leverage is working against you.
Yield on Cost for Development
For ground-up construction, yield on cost uses the same logic with a larger and more complex denominator. Total development cost includes land, all hard costs (materials, labor, general contractor fees), and soft costs like architecture, engineering, permitting, and legal work. Financing carry, the interest accruing on a construction loan while the building isn’t yet producing income, also gets added to basis.
Because a development has no income during construction, the NOI in the numerator is projected stabilized income once the building is leased up. That introduces forecasting risk that doesn’t exist for an operating asset. Stabilized NOI is an estimate, and development costs routinely exceed initial budgets. Both realities tend to compress actual yield on cost relative to the underwritten figure, which is why experienced developers build contingency into their projections.
Judgment Calls That Move the Number
One of the quieter disagreements in commercial real estate analysis is whether replacement reserves belong above or below the NOI line. Replacement reserves are funds set aside for future capital expenditures like roof replacements, elevator modernizations, and parking lot resurfacing. They aren’t a cash expense today, but they represent a real future cost.
The OCC’s guidance takes the conservative position: reserves should be deducted from income when calculating NOI, even though they aren’t a cash outflow every period. Many equity investors take the opposite approach, excluding reserves from NOI to keep the figure comparable across properties and then accounting for capital needs separately in their cash flow models. Neither method is wrong, but they produce different NOI figures and therefore different unlevered yields. When comparing two opportunities, make sure both are treating reserves the same way.
Properties needing more than 15–20% of NOI in annual capital reserves are generally signaling excessive maintenance relative to income. That’s worth investigating before trusting the yield number.
What Unlevered Yield Doesn’t Tell You
No single metric tells the whole story, and this one has blind spots worth naming. It’s a single-year snapshot that says nothing about how income will change over the holding period. A property with a strong current yield but leases rolling to below-market rents next year is a very different investment from one with locked-in escalations running another decade, even at the same unlevered yield today.
It’s also a pre-tax, cash-based figure. It ignores depreciation and any tax shelter the property produces, so the after-tax return can look quite different from what the yield suggests. And it ignores the time value of money entirely: a 6% first-year yield tells you nothing about whether ten-year total returns will be adequate, because it doesn’t account for rent growth, capital expenditure timing, or sale proceeds. For that, you need a discounted cash flow analysis modeling income and expenses year by year.
Unlevered yield works best as a screening tool and a benchmark for current earning power. It’s the beginning of underwriting, not the end of it.
